2, Figure 2, represents a number of main dials which register the totalof the numbers which are added together. These dials consist preferablyof cup-shaped wheels which are numbered on their periphery and aremounted in their proper order on a transverse dial shaft 3, which isjournaled in bearings on 4 the main frame, the dials being so arrangedthat the dial representing the lowest number is arranged on the righthand end of the series and the dials representing the successivelyhigher numbers being arranged successively in their order toward theleft from the dial representing the lowest number. The lowest or righthand dial is preferably divided on its periphery into eighths so as toindicate fractions of a cent in eighths, and the remain ing dials aregraduated on their periphery according to the decimal system intotenths. As shown in the drawings, ten total dials are shown and extendfrom fractions of a cent to tens of millions, but if desired, additionaldials may be added to the right and to the left of the series. if it isdesired to register smaller divisions of a cent or more than tens ofmillions. Each of the main total dials 2 is pro- I vided on its lefthand side with a gear pinion 4, which is rigidly connected therewith, asshown in Figure 2. The pinion of the fraction wheel has eight teethwhile the pinions of the remaining dials are each provided with tenteeth. 5 represents the main registering gear segments, one of which isprovided for each of the dials 2 and is adapted to engage with thepinion thereof. for operating the respective dial. Each of these gearsegments is arranged in rear of its companion gear pinion and isprovided at its lower end with a rearwardly projecting arm 6 which ispivoted loosely on a transverse supporting rod 7. This rod is mountedwith its ends on the upper ends of two rock arms 8 which turn loose lywith their lower ends on a transverse. rockshaft 9. The rock-arms 8 areconnected by a transverse bar 10 which compels the two arms to move backand forth together. In the nor .mal position of the gear segments whenthe machine is at rest these segments are retracted rearwardly out ofengagement with the dial pinlons of the dials and the segments areelevated so that their lowermost teeth are opposite the space betweenthe adjacent teeth of the dial with the pivots of the segments.

The gear segments are yieldingly held backwarclly out of engagement withthe dial pinions by means of springs 11 connecting the rock-arms 8 witha stationary part of the frame. Figure 9 shows one of the springs 11connecting one of the rock-arms 8 with a transverse stationary bar 12 inthe rear part of the machine. moved forwardly so that 'their teethengage with the dial pinions 4 by means of a shifting rock-arm 13, which.is preferably secured to the right hand rock-arm 8 and projectsrearwardly. Upon raising the shifting rock-arm 13, the rock-arms 8 areswung forwardly and the gear segments 5 are enaged with the dialpinions. While upon swinging the shifting rock-arms downwardly, the rockarms 8 are swung rearwardly and the gear segments are disengagedfrom thedial pinions. v

1 1 represents a cam whereby the gear'seg ments are engaged with thedial pinions.

p1n1ons and the gear The gear segments are This cam is mounted on theupper portion of a vertically swinging rocking frame 15 which isarranged on the right hand side of the machine. This cam is provided atits front end with an incline or cam face 16 and at its rear end with aconcentric, face 17 When the cam is in its rearmost or retractedposition, its incline stands in rear of a roller or projection 18 on therear end of the shifting arm 13 as shown in Figures 2 and 10. Uponswinging the rocking frame 15, so that the cam 14 moves forwardly, theincline of the latter engages underneath the roller 18 and raises thearm 13, thereby moving the arms 8 forwardly. The throw of the incline 16is just suflicient to engage the teeth of the gear segments with thedial pinions. When the roller 18 has been raised to the top of theincline, the concentric portion of the cam enaffect the arm 13 and theparts connected therewith, but is affected by said arm at the lastportion of the backward movement of Y the cam, at which time the back orlower side of incline 16 engages with the roller 18 which lifts saidincline and at the end of the backward movement of the cam, the latterclears said roller and drops behind the same, as shown in Figure 2,preparatory to again ra1sing the roller 18 and connecting parts duringthe next forward movement of the cam 14.

For the purpose of permitting the front end of the cam to rise so as toclear the roller 18, this cam is pivoted at its rear end to the rearportion of the rocking frame 15, The upward and downward movement of thefront end of the cam is limited b means of a lug projecting from theside of t e camand engaging with a slot in the adjacent part of wherebysaid shaft is rocked and the parts connected therewith are operated.

The gear segments 5 are raised to their highest position by means of areturn or lifting bar 22 which extends transversely underneath all ofthe arms 6 of the gear segments and which is connected loosel at itsrear ends with the transverse rod 7 by ifting plates 23. 24: representstwo shifting arms which are ment with the transverse bar 25.

' forwardly during permitted to move downwardly with the bar until thesegments are arrested.

Each of thegear segments is yiel-dingly held in contact with the liftingbar 22 by a spring 27 which connects the arm of the seg- If the downwardmovement of the gear segment is arrested while the shifting arms 24continue to move downwardly, the lifting bar 22 is moved away from theunderside of the arm of the gear segment and the spring 27 is strained.The transverse bar 25 is arranged at one end in a segmental notch 28formed in the front part of the rocking frame 15, shown in Figures 2 and10, and its opposite end is arranged in asimilar segmental notch 28,formed in a rocking frame29 (Fig. 10) which is secured to the operatingshaft 20 on' the left hand side of the machine. The rocking frames 15and 29 together with the operating shaft 20 constitute the main oruniversal operating frame of the machine.

When the machine is at rest, as shown in Figure 2, the transverse bar 25engages with the front side of the notches 28 in the rocking frames 15and 29. Upon turning the rocking shaft 20 forwardly, by means of itshandle 21, in the direction of the 'arrow, Figure 2, the roc (ing framesare moved the first part of the movement independently of the transversebar 25. The latter remains at restuntil the inclined front end 16 of thecam 14 has raised the arm 13 and moved the gear segments into engagementwith the dial pinions, during which movement the rocking frames moveidly the extent of their notches 28 along the ends of the bar 25 withoutdisturbing the latter. After the gear segments have been engaged withthe dial pinions, the. continued forward movement of the rocking framescauses the rear ends of their notches 28 to engage with the bar 25 anddepress the same, thereby causing the lifting bar 22 to be moveddownwardly and strain the springs 27. This causes all of the gearsegments which are free, to be moved downwardly and to continue theirdownward movement until they are arrested. During the downward movementof the gear segments, while they, are in engagement with the dialpinions, the latter and the dials connected therewith are. turned untilthe downward movement of the segments is arrested. The extent which eachdial is turned depends upon the position in which the downward movementof its operating segment is arrested. After the segments have beenarrested in their downward movement, they remain in this position whilethe rocking frames complete their forward movement. At the end of theforward movement of the rocking frames, the roller 18 of the rock arm 13drops off from the rear end of the concentric part of the cam 14,thereby allowing the springs 11 to pull the gear segments rearwardly outof engagement from the dial pinions. v

Upon now turning the rock-shaft 20 backwardly by means of the handcrank, Figure 10, the rocking frames are moved backwardly until thefront ends of the notches engage with bar 25. \Vhen the latter is soengaged it is moved backwardly with the rocking frames to the end oftheir rearward movement which causes the transverse bar 25 to lift thelifting bar 22 and the" gear segments which have been depressed intotheir highest or normal position. During this upward movement of thedepressed gear segments they are out of'engagement with the dialpinions, so that the dials are not turned backwardly with the segments,but remain in their shifted position. 30 represents a number ofelbow-shaped controlling arms, which form part of the devices wherebythe downward movement of the registering gear segments is controlled.One of these arms is'arranged along the left hand side of each gearsegment and consists of an upright front part and a horizontal lowerpart which extends rearwardly from the lower end of the upright part,thereby leaving a clear space in rear of the upright part of thecontrolling lever, as represented in Figures land 2. The rear end of thelower part of each controlling arm is mounted loosely on .a transversesupporting bar 81, while the upper end of its front or upright part isloosely connected with the upper portion of its companion gear segment.This loose connection permits the controlling arm and the gear segmentto swing freely about their individual axes, which are arranged parallelbut out of line, and also permits the gear segment to move forward andbackward into and out of en-, gagement with its companion dial pinion.The transverse stop bar 32, (Fig. 2) definitely limits the upwardmovement of the controlling arms. Each controlling arm is'provided onthe rear part of its upper end with a locking lug 33, and on the frontpart of its upper end witha stop lug 3 1, both of which lugs projecttoward the left and are preferably stamped out in one piece with thecontrolling arm.

The operation of the registering device is controlled by a number ofelbow-shaped key levers which are arranged side by side and pivoted to atransverse supporting rod 35.

All.

Each key lever is provided with a lower actuating arm 36, which projectsforwardly, and an upper stop arm 37 which projects upwardly along theleft hand side of one of the controlling arms and gear segments asrepresented in Figure 2. Each of these key levers is provided onthe rearside of its stop arm with a locking shoulder 38 which is adapted toengage with the locking lug 33 of the controlling arm when the latter iselevated into its highest position and the keylever is in its fullyretracted position, as shown in Figure 2. When the parts are in thisposition, the key lever holds the controlling arm against downwardmovement and the latter holds the gear segment against downwardmovement. If the gear segment while so held against downward movement ismoved forward into engagement with the adjacent dial pinion, and therocking frames are turned forwardly for depressing the gear segment, thespring 27 ofthis segment will be strained without however, shifting thewardly thereon,

segment. At the end ofthis forward movement of the rocking segments theroller 18 of the rock-arm 13 drops off from the rear end of the cam 14,the gear segment is moved rearwardly out of engagement from the dialpinion and then the rocking frames move ackwardly without having shiftedthe dial. s The upper arm of each key lever is provided on its frontside with a verticalfseries of differential stop shoulders 39, whicharearranged step fashion and extend from the upper end of this armdownwardly and foror in other words the stop shoulders 39 are arrangedradially out-of line with one another and different distances from thepivot of the key lever, These stop shoulders of the key lever areadapted to be moved forwardly into the path of the stop lug 34 of thecontrolling arm. The stop shoulders are arranged different distancesfrom the stop lug 34 of the controlling arm, so that by moving differentstop shoulders of the key lever into the path of the stop lug of thecontrolling arm, the latter and the gear segment connected therewith maybe arrested at different points in their downward movement. Theuppermost stop shoulder of the key lever is most remote from the. stoplug of the controlling arm, and therefore requires the greatest forwardmovement of the key lever, in order to bring this stop shoulder into thepath of this stop lug. The stop shoulders of the key lever are soarranged that the distance from the stop shoulders to the path of thestop lug gradually grows less from the uppermost stop shoulder to thelowermost stop shoulder. The relative position of the different stopshoulders of the key lever is such that when its locking shoulder 38remains in engagement with the locking lug 33 and the gear segment issimply moved into and out of engagement with its dial pinion, the latterremains at zero, if the same has not been previously moved. But when thekey lever has been moved forwardly, so as to disengage its lockingshoulder from the locking lug and moves one of its stop shoulders intothe path of the stop lug of the controlling arm, the latter arm and gearsegment connected therewith will be moved downwardly upon movingtherocking frames forwardly, until the stop lug of the controlling armstrikes the respective stop shoulder of the key lever which stands inits path, whereby the gear segment while turning in engagement with theadjacent dial gear pinion turns the same forward. By turning the keylever forward more or less and moving one of the other of its stopshoulders into the path of its stop lug 34 of the controlling arm, thedistance which this arm descends can be varied, thereby varying thenumber of spaces which its gear segment turns the adj acent' dial.

Main number key mechanism 40 represents the main keys whereby the keylevers of the main registering and recording mechanism are operated, andWlllCh are guided with their depending stems in the top 41 and thebottom 42 of the keyboard. As shown in the drawings, nine longitudinalcolumns of these keys are arranged transversely side by side. The firstcolumn on the right-hand side of the machine contains seven keys andrepresents fractions of one-eighth of a cent, the next column toward theleft contains nine keys and represents cents and the remaining columnsof keys toward the left each contains nine keys and representprogressively-higher orders of numbers according-to the decimal system,so that the registering keys in the last or left hand column representhundreds of thousands of dollars. V

The lowest 'numbers of the several columns of keys are arrangedtransversely in a row on the rear part of the keyboard and thecorresponding higher numbers of the several columns are arrangedlikewise in transverse rows and progressively in their order towar thefront end of the keyboard.

Each of the registering keys is yieldmgly held in an elevated positionby a spring 43 surrounding the stem of the key and connected at itsupper end to the key and hearing with its lower end against the bottomof the keyboard. The upward -movement of each key is limited by ashoulder 44 formed on the upper part of its stem and engaging with theunderside of the top of the keyboard. The downward movement of all ofthe keys is substantially the same, but the arrangement of each columnof keys lengthwise of the lower actuating armof each key lever causesthe keys to bear against their lever at different distances from itspivot, so that by depressing most stop shoulders are shifted into thepath of the stop lug 34 of the respective controlling arms. The throw ofeach key lever upon depressing any one of its keys is so adjusted, thatthe proper stop shoulder on its upper arm is'inoved into the path of thestop lug 34 of the controlling arm, and the downward movement of therespective gear segment is arrested after having turned the adjacentdial gear pinion a number of spaces corresponcL ing to the number of thekey which is depressed.

Loose connection for segments The loose connection between eachcontrolling arm and its gear segment, heretofore referred to, is shownin its simplest form in the connection between the controlling arm andthe gear segment, which are controlled by the initial or lowest columhof registering keys. As shown in Figures 1 and 12 the loose connectionbetween the controlling arm and the gear segment of the lowestregistering ,device consists of upper and lower guide lugs 45 and 46arranged on the upper end of the seg ment and bearing against the upperand lower guide faces 47 and 48, which are formed on the upper end ofits companion controlling arm. As the controlling arm and segment riseand fall, the guide lugs of the segment slide back and forth on theguide faces of the arm. The guide faces are so constructed that the backand forth movement of the seg ment on the arm is radial with referenceto the dial pinion in all positions of the segment. By so forming the.guide faces of the arm, the gear segment can be engaged with anddisengaged from the dial pinion in all positions of the segment withoutdisturbing the position of the dial pinion. 4 The construction of theloose connections between the controlling arms and gear segments of allof the higher registering devices above the fractional reg1steringdevice is combined with carrying devices, whereby each registering dial,upon making one complete turn, causes the next higher dial to be turnedforward one space,

thereby carrying up a. number from one order to the next higher order.The loose connections between the controlling arms and the'segments-andthe carrying mechanism of the higher registering devices are constructedas follows 7 As shown in Figures 1, 2 and 11, each controlling arm isprovided at its upper end.with

upper and lower guide faces 47 and 48 and its lower guide face isengaged by a lower he same as in coupling between the controlling armand segment of the initial registering device. The gear segments of thehigher registering devices are each provided with an upper guide lug 49which is adapted at times to bear against theupper guide face 47 of thecompanion controlling arm in substantially the same manner in which theup per guide lug 45 of the fractional gear segment bears against itscompanion arm, the only difference being that the upper guide lugs 49 ofthe higher gear segments are held out of engagement and separated by aspace from the upper guide face of the companion arm whenno number iscarried from a lower to a higher registering device. The upper guide lug49 is held in this elevated position above the adjacent guide face byarocking latch 50 which is arranged in a notch in the rear side of thegear segment and which normally projects toward the left and engageswith the upper guide face 47 of the adjacent controlling arm, as shownin Figures 2 and 11.

During the ordinary up and down movement of each highercontrolling armand gear segment, the latter is guided by its lower guide lug 46 and thelocking latch 50 engaging with the lower and upper faces of theadjacent' arm, this movement being the same as the movement of thecontrolling arm and gear segment of the fractional registering device.Normally the downward movement v of the controlling arm is determined bythe position of its companion key lever and this armin turn controls theextent of the downward movement of the gear segment. When, however, thelocking latch 50 is withdrawn out of engagement from the upper guideface 47 of the arm, the companion gear segment is capable of movingdownward independently of the arm until the upper guide lug 49 engageswith the upper guide face of the arm. The extent of this independentmovement of the gear segment with reference to its companion arm isequal to one tooth or space of the segment, so thatby this means thegear segment is enabled to turn the dial ,plnio'n one space more thanthe position of the key lever permits the same to move. I The withdrawalof the locking latch of each higher registering device is controlled bythe next lower registering device and the withdrawal of each latch iseffected when the next lower registering device has made one completeturn and arrived at zero. Each of the locking latches is pivoted on theright hand side of its adjacent gear segment, so

as to turn transversely with reference to the latter. The latch isturned toward the left into its operative position by a spring 51, themovement in this direction being limited by a shoulder 52 arranged onthe latch and I bearing against the right hand side of the guide lug 46on the adjacent gear segment,

gear segment. 53 tFig. 11) is an upright each latch and arrangednormally at right angles or nearly so to the adjacent gear segment, whenthe latch is in its operating position. 54 (Fig. 4) represents a numberof upright trip arms, each of which is controlled by a lower registeringdevice and which turns the locking latch of the next higher registersits lowermost point near the axis thereof and then extend outwardly in aspiral line terminating with its highest point in line with itslowermost point with which its connects radially and abruptly. The tripcam of the fractional registering device has its face divided into eightparts, each part of which except the first is arranged one-eighth of aspace further from the center of the cam than the preceding part, whilethe trip cams of the higher registering devices each has its facedivided into ten parts, each part except the first being arrangedone-tenth of a space farther from the axis of the cam than the precedingpart. Each of the trip arms 54 extends upwardly along the right-handside of the trip camw of a lower registering device, and its shoulder 56engages with the face of this cam, while the hook 55 at its upperendextends toward the left and is adapted to engage with the trip plate53 of the next higher registering mechanism. ltn the initial position ofeach trip arm, its shoulder 56 engages with the lowest part of its tripcam, as

represented in Figure 2. As thetrip cam is turned in the direction ofthe arrow, Figure 2, at the same time that its dial and gear pinions aremoved forwardly by the adjacent gear segment during the addingoperation, the trip arm is moved backwardly by the gradually rising faceof the trip cam. During this backward movement of the trip arm, its bookengages with the trip plate 53 of the next higher registering device andis deflected toward the right thereby, the hook being sufficientlyelastic for this purpose. After the hook has passed in rear of said tripplate, the hook owing to its resilience springs back to its normalposition, so as to stand behind said trip plate. When the shoulder ofthe trip arm reaches the highest part of the face on the trip cam thetrip arm has been shifted to its rearmost position. Upon now turningthis cam forwardly another space together with its companion dial andpinion, the highest part of the cam is carried from underneath theshoulder of the trip arm and the latter is moved forwardly over theabrupt face of the cam until its shoulder 56 again engages with thelowest part of-the cam face. During this movement of the trip arm, itshook strikes the rear side of the trip plate 53 of the next higherregistering mechanism and turns the same forwardly, thereby disengagingthe locking latch from the adjacent controlling arm and permitting thegear segment carrying the trip plate to move forward one space. Theforward movement of the trip arm is effected when the dial with whichits trip cam is connected has made one complete rotation and againstands at zero, whereby the addition represented by this completerotation is carried to the next higher registering device. The forwardmovement of the trip arm is effected quickly by a spring 58, whichconnects with a stationary cross bar 59 arranged in front of the triparms. The trip plate 53 of each registering device is so arranged and isof such length that the hook of the next lower trip arm cam engage withthe rear side of the plate, for disengaging its latch in any position ofthe gear segment carrying the plate, and in order to accomplish thisengagement itis obvious that cams 57 should be constructed so as to givearms 56 the propor throw. If a gear segment is locked in its highestosition by reason of none of its companion eys having been depressed,the withdrawal of its latch from the controlling arm simply permits thegear segment to drop one'space and turn its companion dial pinlonforward one space, while in engagement therewith, the movement of thisdial representing one number carried up from the next lower dial. If anyone of the keys of the key levers has been depressed, so as to releasethe gear segment and permit the same to move downwardly for effecting anaddition, and if during this time the next lower registering device hasmade a complete turn, so as to require the carrying up of a number fromthe next lower registering mechanism, the latch of the higherregistering device will be withdrawn while the same is effecting itsaddition, thereby causing the segment todescend and turn its'dial onespace in addition to the space corresponding to the depression of itsrespective key.

When the locking latch has been withdrawn so as to permit a gear segmentto move downwardly one space farther than its controlling arm, the latchremains in this position during the subsequent upward movement of thearm and the segment, until the upward movement of the arm is arrested bystriking the stop bar 32, and the gear segment continues its upwardmovement independently of the arm the extent of one space. The gearsegment has now reached its highest position and its latch is againswung automatically by its spring over the controlling arm. Thecontrolling arm and gear segment now remain in this relative positionuntil another number is to be carried up from the next lower registeringdevice.

When the controlling arm has been retracted to its highest position, theadjacent key lever is moved into its normal retracted position, so thatits locking shoulder 38 engages with the locking lug 33 of thecontrolling arm and locks the latter against downward movement. Thereturn movement of each key leveris preferably effected by a spring 60which connects the upper arm of the key lever with the transverse shaft9, as shown in Figure 2, or with some other convenient part of-themachine. The lower cents.

guide lug of the gear segment is not absolutely necessary because theweight of the parts connected with the controlling arm and arranged inrear of its pivot is sufficient to raise the arm, but it is preferableto employ this lower guide lug 46 on the gear segment because it compelsthe arm to rise with the gear segment and avoids displacement of theseparts with reference to each other, and also serves as a stop to limitthe upward movement of-the gear segment.

The gear pinion and the co-operating gear segment of the fractionalregistering device are so constructed that the fractional dial makes onerotation whenever it is moved forward eight spaces. .After thefractional dial has made one rotation the whole number represented bythis rotation is transferred by the first carrying device from the.registering mechanism of the fractional dial to the next higherregistering device which represents he complete turns of each of thefollowing registering devices are in like manner carried or transferredto the next higher dial by the respective carrying device. The dialwhich records the highest number, in this instance the millions ofdollars is preferably operated only by the adjacent car-rying device ofthe next lower dial and is incapable of being operated directlv from thekeyboard because'it,is not provided with a. key operating mechanism.

The mechanism whereby the dials are all turned back to zero or the placeof beginning after the addition of numbers has been completed isconstituted as follows:

61 (Fig. 2) represents a series of feeling rock levers which are adaptedto shift the key levers, so as to permit the gear segments Loosely onthe supporting bar 35 adjacent to" the left hand side of each of the keylevers and is provided on its upper arm with a forwardly projectingfeeling finger 62 and with a shifting finger 63 which extends laterallybehind the upper arm of the adjacent key lever. The feeling levers havetheir fingers arranged in rear of the total cams 57, and

each of these levers is turned so that its uprepresents a transversepull bar arranged in rear of the lower arms of the feeling levers andconnected with each of .the latter by a pull spring 65, as representedin Figures 2 and 10. "lhis pull bar is connected at its ends to thelower ends of two depending pull or rock arms 66, which are secured attheir upper ends to the rock shaft 9 as shown in Figure 10. Upon turningthis rock-shaft, so as to swing its depending pull arms backwardly thefeeling levers are turned by means of the springs 65 so as to move theupper arms of these levers forwardly. This movement of the rock-shaft 9is effected by a cam (V (Fig. 9), which is mounted on the lefthand sideof the rocking frame 29 and which is constructed substantially the sameas the cam 14 which is mounted on the rockingframe 15. As shown inFigures 9 and 10, this cam is pivoted near its rear end by a transversepin to the rear portion of the rocking frame 29 and is provided at itsfront end with an incline or cam face 68, and in rear of the inclinewith a concentric face 69. The cam 67 is pivotally supported on therocking frame 29 in the same manner in which the like cam 14 is pivotedon its corresponding rocking frame 15. The cam 67 can be raised andlowered with its front end into an inoperative or operative position,this movement being limited by means of a lug 7 0 arranged on the cam asshown in Figure 10, and projecting into a slot 71 in the adjacentrocking frame in the same manner in which the movement of cam 14 islimited.

72, Figures 9 and 10, represents a rearwardly projecting rock-armsecured to the rock-shaft 9 and provided at its rear end with a rolleror projection 7 3 which is adapted to be engaged by the cam 67 forturning the rock shaft 9. When numbers are being added with the machine,the cam l l is depressed, as shown in full lines, Figure 2, so as tobein a position when moved forwardly by the rocking frame 15 to engage theroller on the arm 13, for moving thegear segments into engagement withthe dial pinions, and during this time the cam 67 is lifted into theposition shown in full lines, Figure 9, so that when the rocking frame29 is moved forwardly, the cam 67 will clear the roller 73 of the rockarm 7 2 and not disturb the rock shaft 9 and the parts connectedtherewith.

If it is desired to restore all of the total dials 2 to zero, the cam 14is raised into its inoperative position, shown by dotted lines in Figure2, and the cam 67 is lowered into its operative position, as shown bydotted lines 67 in Figure 9. Upon now turning the rock shaft 20 by handso as to move both rocking frames 15 and 29 forwardly, the cam 14 passesover the roller 18 of the arm 13 without disturbing the same, but theinclined front of the cam 67 engages with the roller 7 3 on the rear endof the rock-arm 72 and raises the same until this roller engages withthe concentric part 69 of this cam. By this movement of the arm 72, therock shaft 9 is turned in the direction for moving its depending arms 66rearwardly and pulling the springs rearwardly. This pull on the springs65 causes the feeling levers to be turned until the feeling fingers oftheir upper arms engage with the spiral surfaces of the trip cams. Afterthe feeling fingers bear against these cams, their movement is arrestedand the continued backward movement of the pull bar 64 simply stretchesthe springs 65 until the bar reachesthe end ofits backward movement. Thefeeling finger of each feeling lever engages with that part of thesurface of the adjacent trip cam which is directly opposite the feelingfinger, and as these trip cams are turned with the-adjacent dials theypresent difi'erent parts of their spiral surfaces to the opposingfeeling fingers, which causes the forward movement of the upper arms ofthe feeling levers to be arrested in different positions when swungforwardly. During the forward movement of the upper arm of each feelinglever, its shifting finger 63 engages with the rear side of the upwardlyprojecting arm of the adjacent key lever and moves this arm forwardly.The construction of the parts is such that the spiral surfaces of thetrip cams bear a definite relation to the step-shaped series of stopshoul ders on the upper arm of the key lever. When the feeling fingerof. the feeling lever, upon being moved forwardly, bears against thelowest key-lever-stop-controlling part of the adjacent trip cam, theadjacent key lever is carried simultaneously forward with the feel inglever the greatest distance audits uppermost stop shoulder is carriedinto the path of the stop lug of the controlling arm. The succeedingparts of the spiral surface of the trip cam are so constructed that theyrise progressively higher and arrest the forward movement of the feelinglever when the same has carried the ad acent key .lever with itscorresponding stop shoulder into the path of the stop lug of thecontrolling arm. This forward movement of the feeling lever and that ofthe upper arm of the key lever is gradually reduced as the progressivelyhigher parts of the trip camvare presented to the feeling finger, andwhen the highest part of the trip' cam is presented to the feelingfinger, the feeling fever is prevented from moving forward at all andthe upper arm of the key lever is not moved with its locking shoulderout of engagement with the locking stop of the controlling arm andconsequent- ,ly the companion gear segment connected therewith is heldagainst downward movement. After the rocking frames 15 and 29 have beenturned forwardly sufliciently to engage the several feeling fingers ofthe feeling levers with their respective trip cams, the rear ends of thesegmental notches 28 in the rocking frames engage with the cross bar 25and depress the same, thereby moving the lifting bar 22 downwardly andat the same time pulling down the springs 27. This downward pull onthese springs causes each spring to pull its respective gear segmentdown as far as possible, and after the downward movement of the segmenthas been arrested the continued downward movement of the cross bar 22together with the rocking frames simply stretches these springs untilthis bar reaches the end of its downward movement. If a gear segment islocked in its uppermost or zero position its spring 27 will be stretchedits fullest extent. whereas, if a gear segment moves downwardly more orless before it is arrested by its shifting key lever, its spring 27 willbe'stretched less in proportion. This downward movement of the gearsegments which are free to move in this direction takes place While thegear segments are in their retracted position and out of engagement-fromthe dial pinions, so that the dials are not affected by this movement ofthe segments.

After the rocking frames have the end of their forward movement and theroller 73 has dropped off from the rear end of the concentric portion 69of the cam 67, the gear segments are moved forwardly by hand operatedmechanism into engagement with their respective dial pinions and areheld in this position during the entire subsequent backward movement ofthe rocking frames, which is effected by hand operated mechanism. Duringthe backward move- .ment of the rocking frames, the gear segvments areraised to their highest positions,

while in engagement with the dial pinions by the rod 22 and connectingparts and turn the dials backwardly. At the end of the upward movementof the gear segments the.

latter are released, so as to permit them to move into their retractedposition, out of engagement from the dial pinions.

During this operation those'gear segments which are held or locked intheir highest positions, by reason of their dials being at zero, aresimply moved forward at the end of the forward movement of the rockingframes, so as to engage with their respective dial pinions and are againrnoved backwardly out of engagement therefrom'at the end of the forwardmovement of the rocking frames, without disturbing their respectivedials. Each of the unlocked gear segments is moved downwardly a numberof spaces corresponding to the number which is regreached sition,

the gear'segments forwardl in their variously depressed positions and ten raising them to their highest po-,

each depressed gear segment will turn its dial backward the same numberof spaces that the gear segment was depressed. Inasmuch as each gearsegment was permitted to descend by its trip cam, feelin lever and keylever the same number 0 spaces vas the number indicated on its dial, thegear-segment subsequently moves upwardly the same number of spacesbefore reaching its highest position, thereby turning its dialbackwardly the same num- "ber of spaces and restoring the same to zero.

The mechanism whereby the positions of the cams 14 and 67 are reversedpreparatory to restoring the dials to zero is constructed as follows:

" The earns 14 and 67 drop into their op- .erative position by gravity.Each of these oams'is provided in rear of its pivot with a tail 75 whichis depressed when it is desired to lift the respective cam into itsinoperative position.- I

76 is a shifting lever which is pivoted at its lower end and is normallyturned so that its upper end is disengaged from the rear 'side of thetail on the cam 14 by a spring 77,

' jects in rear of the mainframe so as shown in'Figure 2. The member 76proas to be 78 (Fig.

accessible for manual operation.

7 9) is a shifting lever which is pivoted be- I pivoted tween its upperand lower arms and arranged with its upper arm in rear ofthe tail of thecam 67'and normally held in engagement therewith by a spring 7 9, asshown in Figure 9.- 80 represents an elbow lever below the bottom of thekeyboard, as represented in that figure, 81 represents a main line-orcord which is connected with the lower arm of the elbow lever 80 andwhichis provided at its rear end withtwo branches 82 and 83. The branch82 connects with the shifting lever 76 above its pivot, and shiftinglever 78 below its pivot. 84 represents a total or shifting key having ade pending stem which is guided in top and bottom plates of the keyboardand which bears with its lower end against the upper armof the, elbowlever 80. Upon depressing the key 84, the elbow lever 80 is turned,.soas to .draw the cords or lines 81, 82 and 83 forwardly thereby movingthe upper end of the shifting lever 7 6 into engagement wlth the tail ofthe'cam 14 and lifting the same the branch 83 connects with the into aninoperative position, while the shifting lever 78 is moved rearwardlywith its upper arm from the tail of the cam 67, thereby allowing thelatter to drop into its operative position. Upon depressing thegearsegments while the parts are in this shifted position, the segments movedownwardly out of engagement with the dial pinions. After the gearsegments have been depressed the are moved forwardly into engagement wittheir respective dial pinions by an elbow lever 85 which 'is connectedwith its lower arm by a line or cord 86 to the rod or bar 7, as shown inFigure 9, or to one of the rock arms 8. I

The elbow lever is turned in the proper direction for this purpose by ashifting key 87 having a depending stem which is guided in the top andbottom of the key-board and which bears against the upper arm of theelbow lever 85 After the gear segments have been moved forwardly intoengagement with .the dial pinions, while in the depressed position, thegear segments are retained in forward position, and at the same' timeraised until they reach their uppermost position, whereby the dials areturned to zero. The shifting key 87 is now released Which permits thespring 11 to move the gear segments rearwardly out of engagement withthe dial pinions. The key 84 is also released, thereby permitting theshifting levers 76 and 78 to resume the positions shown in Figures 2 and9, leaving the-machine .in position to resume adding.

Each of the dials is held against turning while out of engagement withits companion gear segment, by means ofa detent awl 103 which engageswith the front side 0 its companion gear pinion, .as shown in Figure 2.The pawls 103 of the several gear pinions are mounted on a transversepawl bar 104, which is supported at its ends by means of two pawl arms105, which turn loosely upon the suptent pawls are swung forwardly outof engagement with the dial pinions by means of two shifting rods 107which are connected at their rear ends to opposite ends of thetransverse rod 7 or some part moving therewith and each of which isprovided at its front end with a fork or bifurcation 108, which engageswith a pin or shoulder 109 on the pawl arm arranged on the adjacent sideof the machine. As the gear segments move forward into engagement withthe gear pinions, the shifting rods 107 move the detentpawls 103 out ofenill gagement with the dial pinions and when the gear segments movebackwardly the detent pawls are again engaged with the dial pinions bythe springs 106.

Recording mechanism For the purpose of recording the numbers which areadded together'by the above described mechanism a recording mechanism isprovided which is constructed as follows:

140 (Figs. 1, 2, 3, 9 and 10) rep-resents a printing roller or platenwhich is arranged transversely in the upper, rear part of the machineand under the lower side of which the sheet or other article is placedwhich receives the record. 141 represents a number of type segmentswhich are arranged transversely side by side below the platen and whichare pivoted at their front ends to the supporting bar 31 upon which therear ends of the controlling arms are pivoted. Each of these typesegments is provided at its rear" end with a segmental row of typecarriers 142,. which are capable of moving radially back and forth onthe typesegment.

Each of the type carriers is provided at its rear end with a type and isguided upon the type segment by means of screws or rivets 143 (Fig. 5)secured to the type carrier and arranged in radial slots 144 formed inthe type segment, as shown in Figures 2 and 5. Each of the type carriersis held in its inward or platen.

retracted position by means of an S-shaped spring 145, which is arrangedbetween the.

carrier and the type segment and is secured with one end to the carrierand with its other end to the type segment. Upon raising or lowering thetype segment any one of its type can be brought to the printing point orline, and upon striking the back or inner end of the type carrier, whenthe same is in line. with the printing point the-type carrier will bedriven outwardly and its type will produce an impression on the sheetsupported by the After the carrier has received the blow for driving thesame against the platen, the carrier is again quickly retracted to itsinnermost position by means of its spring. Each of the type segments isconnected with one of the controlling arms, so that upon depressing acontrolling arm and the registering gear,segment connected therewith thecompanion type segmentwill be raised and present one of its type to theprinting point. For convenience in operating the machine, the keys areseparated a considerable distance on thekey-board and in order toproduce a compact record, theprinting segments are arranged closertogether than the keys and the registering mechanism. In order to permitof this arrangement, each type segment and its corresponding controllingarm are connected by a connecting arm 146, as represented in Figures 1,2, and 11. The connecting arms of the central controlling arms rmaeaeand type segments are comparatively straight but the connecting arms ofthe outer type segments and controlling arms are arranged obliquely, thedegree of this obliquity gradu ally increasing from "the central typesegments and controlling arms in opposite directions toward the outertype segments and controlling arms, as represented in Figure 1.. Theconnecting arms 146 of the outer controlling arms are arranged in thespaces behind the upright parts and above the horizontal parts of thecontrolling arms, thereby permitting the inner controlling arms to moveup and down without interfering with the connecting arms, 146 of theouter controlling arms.

The types on each type segment are arranged to correspond with the teethand numbers of its companion gear segment and registering dial, the zerotype being at the upper end of the series and the progressively higherdigits arranged in their order downwardly from the zero typeVVhen theregistering gear segment is in its highest postion it presents its zerotooth to the dial pinion, and the type segment which at this time is inits lowest position presents its zero type to the printing point. Upondepressing a gear segment so as to present one of its higher teeth tothe dial pinion, its companion type segment is raised proportionally andpresents a corresponding higher number type to the printing ioint.

1 147 represents a number of hammers whereby the type carriers arestruck for driving the type against the platen. One of these hammers isarranged adjacent to each type segment and is provided with a head whichis arranged in front of the series of tvpes and in line with theprinting point of the platen. Upon shifting the type segment so as tobring one or another of its type carriers to the printing line and thenoperating the hammer, the latter delivers a blow against the inner endof the particular carrier which is at the printing point and produces animpression of its type on the platen. The several hammers are pivoted onthe transverse rod 12, arranged in rear of the segment; and each of thehammers is yieldingly held in its forward position by a spring 148connected at its lower end to a cross bar 149 and at its upper end to adepending arm 150 on the hammer.

151 represents a vertically movable trip bar or rod which is arrangedtransversely below the'hammers and whereby the latter are operated. Thisbar is supported at its ends upon the rear end of rock arms 152 whichturn loosely with their front ends on the rod 31 supporting the typesegments and controlling arms.

153 represents a number of hammer or trip pawls, whereby the hammers areretracted preparatory to delivering a blow against the type carrierswhich are at the printing point.

-One of these pawls is arranged adjacent to each hammer and pivotedloosely at its lower end to the trip bar 151 and its upper end isprovided on its rear side with a downwardly facing hook orshoulder 154,and above said shoulder with a trip face 155, as shown in Figure 6. infront of its pivot adjacent to the upper end of the hammer pawl with alower trip lug or shoulder 156 and an uppertrip lug or shoulder 157.When the parts are at rest, the hammer pawl 153 is raised into its highest osition and the hammer is in its normal pos1tion with its lower triplug 156 below and in-rear of the hook of the hammer pawl and with itsupper shoulder 157 in rear'of the trip face" of the hammer pawl,asrepresented in Figures 2, 5 and 6.

\ Upon shifting the hammer pawl rearward ly, while the parts are inthisposition, so that its hook overhangs the lower shoulder 156 of thehammer, and then pulling the. hammer pawl downwardly, the hook of thehammer pawl engages with the lower shoulder .of the-hammer and turns thesame so. that its head is retracted from the type carrier at theprinting line. As the hammer moves downwardly with the hammer pawl, theupper shoulder of the hammer comes into engagement with the trip face ofthe hammer pawl and during the continued downward movement of the hammerand its pawl, this upper shoulder gradually crowds the hammer pawlforwardly with reference to the hammer,,by reason of the hammer and itspawl swinging on different centers. During thelast portion ofthedownward movement,

of the trip bar 151 and the hammer pawl mounted thereon, the pawl iscrowded forwardly by the upper shoulder 157 of the hammer'to such anextent that its hook is disengaged from the lower shoulder 156 of thehammer, thereby liberating the latter and permitting its spring 148 tothrow the same quickly and deliver a blow against the type carrier atthe printing line. The trip bar151 now'rises and carries the hammer pawlinto its highest position, preparatory to again engaging thehammer fordepressing the same.

158 (Figs. 5 and 6) represents a number of upright shifting arms wherebythe hammer pawls are moved rearwardly, so that their hooks engage withthe lower shoulders of the hammers. One of t'hese'arms is arrangedadjacent toeach hammer pawl, and is pivoted at its lower end on the tripbar 151, and its upper end is provided with a roller or projection 159cam 160 on the lower part of the adjacent type segment as shown inFigures 5 and 11. This hammer cam is provided at. its upper end with areceding or lower portion, aninclined portion arranged below the lowportion and a concentric or high portion .ar-

ranged below the inclined portion. Each Each of the hammers is providedwhich bears against a hammer 'with the adjacent hammer cam by a spring161 connecting said arm with a cross bar 162 secured to the rock arms152, as represented in Figure 3. The backward movement of each hammerpawl with reference to its companion shifting arm, is limited by meansof a stop 163 secured to the upper portion of the hammer pawl andengaging with the front side of the shifting arm, as represented inFigures 5 and 6.

Each hammer pawl is yieldingly held in its rearmost position withreference to its shifting arm by means of a C-shaped spring 16 1 securedwith its ends, respectively, to the hammer pawl and its shifting arm, asshown in Figures 2, 5 and 6. In the lowermost position of a typesegment, the receding part of its cam is presented to the roller of theshifting arm 158, which permits the hammerpawl to be retracted into itsforemost position, as represented in Figure 2. Upon depressing thetrip'bar 151 when the parts are in this position, the roller 159 is notengaged soon enough by the incline of the cam 160 to engage the hook ofthe hammer pawl with the lower shoulder of the hammer, before the hookhas passed below this shoulder, but

the particular type at the printing line isproduced. If the type segmentis raised, so as to present one of its lower types to the printing pointor line, the incline of its-cam during the first part of the upwardmovement of the segment moves the shifting arm 158 rearwardly togetherwith the hammer pawl yieldingly connected therewith, so that the hook ofthe hammer pawl stands over the lower shoulder 156 of the hammer. Uponnow depressing the pawl 153, the hammer will be retracted and releasednear the end of the downwardmovement of the pawl, and will be quicklyswung up by the spring 148, thereby delivering a blow against'the typeat the printing'point and producing an impression thereof.

The incline 160 of the type segment cam is so constructed that it throwsthe hammer pawl backwardlyinto an operative position when the segment israised one digit space, and during the continued upward movement of thesegment, the hammer pawl is held in this operative position by the highconcentric part of the segment cam. By thus constructing the typesegment cam its companion hammer pawl is not shifted when the segment isnot raised and its zero type remains at the printing line, but thehammer pawl is shifted into an operative position for producing animpression, if the type segment is raised one or more digit spaces andpresents any Automatic printing of zero 165 (Figs. 5 and 6) represents anumber of transfer or coupling fingers which enable the ciphers in anumber to be printed automatically. One of these transfer-fingers issecured to each of the shifting arms 158, as represented in Figures5 and6, and extends laterally toward the right therefrom into engagement withthe shifting arm of the next lower hammer pawl. If any one of theprinting se ments remains in its lowest position, so that its cipherremains at the printing line and the next higher printing segment hasbeen raised for printing a higher number or digit, the transfer fingerof the higher hamme lr-shifting arm 158 while being moved rearwardly bythe cam of its companion printing segment, is caused to engage with theshifting arm 158 of the next lower hammer pawl and shift the latterbackwardly, so that its hook is carried backwardly over the lowershoulder of the companion hammer. Upon now depressing the trip bar 151,the higher hammer pawl 153 is coupled with its hammer and the next lowerhammer pawl is also coupled with its hammer, whereby an impression ofthe cipher or zero type on the lower segment is produced on the platenat the same time that the next higher number is printed on'the platen.If two ciphers occur in succession in the body of a number, the shiftingarm to the left of the highest order printing segment to be operated forprinting a zero sets the hammer mechanism of said highest zero-printingsegment by means of the transfer finger of said shifting arm, and theshifting arm of said highest zero-printing segment in turn by means ofits transfer finger sets the hammer mechanism of the printing segment ofnext lower order, etc. This operation of producing an impression of thecipher type is effected automatically and renders it possible to printany number of ciphers in succession in the body of a number because thehammer operating mechanism of each segment which remains standing withits upper type at the printing line is controlled by the hammeroperating mechanism of a higher type. segment and in turn controls thehammer operating mechanism of the next lower type segment if the nextlower segment presents a cipher to the printing line. Only the ciphersbelow the highest digit in the number to be recorded are thus printedautomatical- 1y because the printing of a digit depends upon the upwardmovement of a printing segment. thereby avoiding the printing of ciphersahead of the high est digit in the number to be recorded. Thehan'imer-shifting device of the segment which prints the numbersrepresenting units of cents 1s, preferably, not provided with a transferfinger to operate on more springs 166 (Fig. 3) which connect this barwith the transverse rod 12. and the upward movement of the bar 151 isarrested when the hammer operating pawls reach their highest position bya transverse bar 16? (Figs. 2. 3, and 9) which is engaged by the rearends of the rock arms 152. 168 represents a coupling hook, whereby thehammer trip devices are depressed. This hook is pivoted with its upperend to the trip bar 151 and its lower engaging end is provided with anotch having upper and lower shoulders.

In the lowered position of this hook its notches engage with a cross bar169 which is connected with the rock arms 24, as represented in Figure2, so that the hook and the hammer operating devices connectingtherewith a-re actuated from the rocking frames 15 and 29, through themedium of the rock arms 24. In the rearmost position of the .rockingframes, the front ends of their notches 28 bear against the front sideofthe bar 25 to which the gear segments are yieldingly connected and thecross bar169 bears against the rear or upper shoulder of the notch ofthe hook 168, as represented in F igure 2. Upon swinging the rockingframes forwardly the incline of the cam 14 first raises the rock arm 13and shifts the gear segments into engagement with the dial pinions, andafter the segments have been so shifted, the rear shoulders of thenotches 28 in the rocking frames, engage with the cross bar25, so thatthereafter this bar is carried downwardly with the rocking frames andthe gear segments are depressed. During this downward movement of thebar 25 with the rocking frames, the companion bar 169 moves downwardlyin the notch of the hook 168 until this bar engages with the lower orfront shoulder of this hook. After the cross bar 169 engages with thelower shoulder of the notch of the hook, the latter and the hammeroperating devices connected therewith are moved downwardly with therocking frames until these frames reach the end of their downward'movement. During the last portion of the downward movement of therocking frames the hammer pawls are disengaged as before described, fromthe retracted hammers, whereby the latter are released and strike thetype carriers which are at the printing line. By this means the blow ofthe hammers is delivered after the registering of the numbers has beeneffected on the dials and the type segments have been shifted into theirproper position for recording the respective number.

The hammers do not follow the type caroutwardly by the impact of thehammers and "are then returned by their springs so asto clear theprinting surface.

shifting key N on? print me cham'sm Vhen it is desired to only add thenumbers and not record the'same, the coupling hook 168 is raised withits notch out of engagement with the cross bar 169, which allows therocking frames and connecting parts to move back and forth withoutaffecting the hammerhpen' ating devices. The conpling hook is disengagedfrom the cross bar by means of an elbow lever 171 secured to atransverse rock shaft 17 2. The lower arm of the elbow lever isconnected with the shaft 20 by a spring 173 whereby the lever and theshaft carrymg the same are turned inthe direction for disconnecting theupper arm ofthe lever 171 from the hook 168, thereby permitting thelatter to engage the bar 169. 17 4 (Fig. 9) represents an elbow leverarranged below the bottom of the key-board and connected by a line orcord 175 with its lower arm to the upper arm of the elbow lever 171. 176represents a having a depending stem which is guided in the top andbottom of the keyboard and which engages with its lower end against theupper arm of the elbow lever 174. Upon depressing this key the elbowlever 174 is turned in the direction formoving the rock arm 171 intoengagement with the coupling hook 168 and disengaging the latter fromthe cross bar 169, thereby throwing the recording mechanism outof gear..Upon releasing the key 176, the rock arm 171 1s permitted to swingbackwardly and allow the couphng hook to engage with the cross bar 169,thereby throwing the recording mechanism into gear: 'When the gearsegments and the print ing segments are thus operated relatively to cthe keys which have been depressed, the numher represented by thedepressed keys is registered and also recorded by the printingmechanism. The addition of further numbers proceeds in like manner,theseveral numbers being added successively by the registering mechanismbut each number is printed individually by the recording mechanism.

When it is desired to print or record the total at the foot of thecolumn of the numbers which have been printed, the operation is asfollows :-The total key 84 is first depressed, thereby raising the cam14 into an inoperative position and lowering the cam 67 into anoperative position. Upon now moving the rocking frames 15 and 29forwardly the feeling levers 61 are turned so as to 7 move their feelingfingers forwardly into enarms 150 engaging with a gagement with therespective cams 57, and at .the same time each feeling lever carries theadjacent key lever forwardly so that its particular stop shoulder 39corresponding to the position of the trip cam 57 and its dial .is movedinto the path of the stop lug 34 of the controlling arml After the keylevers have been thus shifted forwardly into their respective positionscorresponding with their dials, the continued forward movement of therocking frames causes the gear segments while in a retracted positionout of engagement with the dial pinions to be depressed until eachsegment is arrested by the engagement of the stop lug on its controllingarm with the respective stop shoulder of its key lever, whereby eachprinting segment is raised so as to present the type carrier to theprinting point which carries the-type corresponding to the numberregistered on its companion dial. During the last part of the forwardand downward rocking movement of the rocking frames the hammers areoperated and the paron the platen. Upon now swinging the rockofengagement with their companion dial pinions, thereby permittingfurther' numbers to be added to the total already registered on thedials- If, however, it is desired to turn the dials back to zero, afterthe total of the added numbers has been printed or recorded, the gearsegments, while in the retracted lower position which they occupy whileprinting the totals, are moved forwardly into engagement with theirrespective vdial pinions by the depression of the key 87. Upon nowmoving the rocking frames backwardly the gear segments are raised whilein their forward position in engagement with their pinions, whereby eachof the latter is turned backwardly and when the segments reach the endof their upward movement, the dials. have been turned backwardly anumber of spaces corresponding to the number on the dial, therebyturning all of the dials to zero.

Word pfinting mecha m'sm y For the purpose of permitting words to be ingframes backward, the gear segments are raised whilestill in aretractedposition out printed in front of the numbers which are addedtogether the following mechanism is provided:

1411 (Figs. 1 and 3) represents a word printing segment which is mountedloosely on the rod 31 next tothe highest number printing segment of themam number recording mechanism. This segment is provided with a numberof radially movable carriers 1420 (Fig. 3), which arerconstructed thesame as the carriers of the number printing segments and each of whichis provided on its face with a word-type. The words of these types areselected according to the "purpose or business for which the machtne isto'b'e used. ,For instance, if the machine is to be used in a bank,types representing the words Vouchers, Checks, Drafts, Bills, andsimilar words common to the banking business may be used. When themachine is designed for use in a restaurant the words Soup, Vegetables,Meats, Dessert, and other words peculiar to this business may be used.

The position of the word type segment is controlled by a key lever 3000,Figure 3, which turns on the bar '35, is similar to the number keylevers and is provided on the front side of its upper arm 3700 with avertical series of differential stops or shoulders 3900 which areadapted to be engaged by the stop lug 3-100 of a controlling arm 3000;and lever 3600 is also provided with a locking stop or shoulder which isadapted to be engaged by a locking lug 3300 on the controlling arm, asrepresented in Figure 3. The controlling arm 3000 is connected with theword printing segment by a connecting bar 1400. The stop shoulders onthe upper arm of the word key lever are so arranged that upon swingingthis lever so as to carry different shoulders into the path of the stoplug on the controlling arm, the latter will be arrested at differentpoints in its downward or forward movement and the word printing segmentconnected therewith will be stopped at different points in its upwardmovement and present the particular word type in the printing pointwhich corresponds with the shoulder or stop on the word key lever. Theupward movement ofthe controlling arm 3000 is limited by its rearlooking lug 3300 engaging with the stop bar 32 which arrests the upwardmovement of the cont-rolling arm 30 of the number registering andrecording mechanism. The downward movement of the controlling arm 3000and the simultaneous upward movement of theword printing segment areeffected by a spring 215 which yieldingly connects this arm with the bar25 to which the registering gear segments are connected.

216 represents a row of word keys having depending stems which areguided in the top and bottom of the key-board and which ongage againstthe upper side of the front arm 3000 of the word key lever at differentdistances from the fulcrum thereof. Upon depressing any of the word keysthe word key lever will be turned the proper distance to bring itsproper stop shoulder into the path of the stop lug of the companioncontrolling arm and arrest the word type segment during its upwardmovement, when the word typo corresponding with the word of thedepressed key has reached the printing line. "When the respective wordtype is in this position the same is driven against the recordingsurface for producing an impression thereon, at the same time that theprinting of the nun'ibcrs by the numbering printing segments iscffected. The word. types are driven against the platen by a hammeroperating mechanism which is constructed the same as the hammeroperating devices of the number printing mechanism and the same lettersof reference are therefore used to denote the same. The word key leveris yieldingly held in its normal position by a spring 600.

00cm ting meal: an ism An auxiliary adding or counting mechanism isprovided which permits of rcgister ing the number of adding andrecording operations which have been made by the main adding mechanism.This mechanism is constructed as follows:

2000 Fig. 4) represents a number of auxiliary dials which are mounted onthe left hand end of the dial shaft 3. 5000 (Figs. 1, 4C, and 7)represents a number of auxiliary gear segments which are mounted on thetransverse rod 7 and are adapted to engage with gear pinions 100 on theauxiliary dials, as represented in Figure 4. Each gear segment 5000 isconnected with a controlling arm 3001 arranged adjacent to the gearsegment by a latch or coupling which at times permits the segment tomove independently of the controlling arm. 3001-3701 (Fig. 1) representauxiliary stop levers which in the original application are combinedwith auxiliary key mechanism, but for the purpose of the pres entapplication these levers may be considered as merely for the purpose ofmaintaining the gear segments and controlling arms in normal position,and controlling the clearing operation.

Printing segments are shown in Figures 1 and 4 as connected with thetuxiliary controlling arms but these form no part of the presentinvention and might be replaced by any other suitable counter weight.The combinations in which the auxiliary key mechanism and the auxiliaryprinting segments form elements are claimed in the parent application1,004 and in other divisions thereof, to which reference is hereby made.

Thedetail construction of the dials, gear segments and parts connectedtherewith is substantially the same as the construction of the sameparts in the main registering and recording mechanism, except ashereinafter distinguished, and the same letters of reference aretherefore employed to denote like parts in both of these sets ofmechanisms.

In the drawings, suilipicnt registering mechanism is shown for countingto 000, but additional registering mechanism may be employed it it. isdesired to increase the capacity of the machine.

In the counting mechanism, each of the higher gear segments 5000 isprovided with a pivot latch 501 (Fig. 7) the same as in the mainregistering mechanism. The lowest or primary gear segment of theauxiliary registering mechanism is provided with a movable 1 panionguide arm,

on the segment adjacentto the latch bears se ment.

against the controlling arm. The extent of this drop of the primarysegment independent of its controlling arm is equal to one spaceor-number' of the registering mechanismthe same as in the highercounting mechanisms.

In the counting mechanism, the gear segments are not provided with lowerstops 46, which in the parent application and in certain other divisionsthereof, permits the printing mechanism to work independently of theregistering mechanism, but for the purpose of the present application,the stop 46 might be used if desired, the same as in.

the mam registering and recording mechanism. The upward movement of theauxiliary or counter gear segments is limited by stops 218 with whichthe upper ends of the gear segments engage. 219 represents a foot formedon the lower side of each controlling arm 3001 and adapted to engagewith the lifting cross bar 22.. 220 represents springs whereby thecontrolling arms 3001 are connected with the cross bar 25.

222 (Fig. 7) represents a number of stops whereby the counting gearsegments, when in their foremost position, are permitted to movedownwardly only one space to count the number of additions which havebeen made by 'the main registering mechanism. One of these stops isarranged adjacent to the left hand side of each controllingarm 3001 andis provided on the upper side of its rear end with a curved guide facewhich corresponds to and is in line with the upper curved bearing faceof the controlling arm when the latter is in its highest position, asrepresented in Figures 4 and 7. The several stops 222 are secured withtheir front ends to a member 223 which in the parent application and insome of the other divisions is movable, but for the purpose of thepresent application this member 223 may be considered as stationarilypositioned with the stops 222 in the downward path of the stop lugs 490and latches 501 and 502.

227 represents a trip finger secured with its front end to the member223 and arranged with its rear end adjacent to the front side of thelatch 502 of the units counter gear revious to beginning the consecutivecounting of the separate additions of the main'registering mechanism,the dials are all the latch rearwardlyturned to zero, all of the upperkey lever arms3701 are in their rearmost positions and have theirlocking shoulders 38 in engagement with the locking lug 33 of thecontrollingarms 3001, whereby the latter are held in their highestposition. Upon moving the rocking segments 15 and 29 forwardly afterdepressing the proper keys of the numher to be added on the mainregistering mechanism, the gear segments are all moved forwardly intoengagement with their re spective dial pinions and the springs 27 of theseveral gear segments are then pulled downward by the bar 25.

During the forward movement of the auxiliary tens and hundreds gearsegments their latches 501 engage with their companion controlling armswhich prevent these gear segments from being depressed by the pull oftheir springs 27, whereby the tens and hundreds dials are not turned.During the forward movement of the primary .or units gear segment itslatch 502 engages with the trip finger 227 and is turned backwardly outof engagement with the top of its companion controlling arm, therebyreleasing the units gear segment and permitting the same to be pulleddownwardly by its spring 27, while in engagement with its gear pinion,whereby the units counting dial is turned. As the gear segments 5000move forwardly into engagement with the dial pinions, their lugs 490move over the stops 222, but in the foremost position ofthese gearsegmentstheir stop lugs 490 are separated from the stops 222 a distanceequal to one tooth of the segments or one space on the dials. Theinstant the latch 502 of the units gear segment is released from theunits controlling arm, while the units gear segment is in its forwardposition the pull of thespring 27 depresses the units segment until itsstop lug l90 engages with the units stop 222, this movement of the unitsgear segment causing the same to turn the units dial one space ornumber. During the subsequent backward movement of the rocking segments15 and 29, the auxiliary gear segments are withdrawn rearwardly from thedial pinions. While in this rearwardly retracted position the units gearsegment is raised by the bar 22 and when the same reaches the upper endof this movement the latch 502 is automatically turned engage the latch501 of the tens gear segment from the tens controlling arm, whereby thetens gear segment is liberated and permitted to be pulled downward byits spring 27.
